Quoted from Kissakala
The problem, however, comes in when you're about to push the enemy's last. It makes it almost impossible for the enemies to hold the point, when your teammates are getting extra health + the speed buff for 10 seconds. To some extent, it's like having an extra medic with you.But you STILL have to get that charge in the first place, which is difficult anyways and requires a lot of passive play, where nothing happens. During that time defending combo is practically safe from bombs, and that's important. because a well-timed bomb can throw off the entire defense.
